WDMyCloud package Docker version 19.03.2, build 6a30dfc

Hello

I have a problem to start the dockerd daemon. Here is the output from my terminal window:

Can someone help how to resolve this?

Thank you in advance

Very Strange, the output today is different:

What specific My Cloud model do you have?

If you have a multi bay model see the specific sub forum for it…
